INDUCTION APPARATUS FOR VENTILATING.

SPECIFICATION forming part of Letters Patent No. 505,231, datedSeptember 19, 1893.

Application iiled August 23, 1892.

To a/ZZ whom t may con/cern,.-

Be it known that I, MARTIN ROSE RUBLE, a citizen of the United States,residing at Newark, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements in Induction Apparatus forVentilating; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others Ioskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

My present invention has for its object the ventilation of street andrailroad cars, vessels, &c., and relates to such ventilators as areoperated by draft or air current, and are simple in construction,durable, reliable and zo efficient in operation.

The invention consists in the improved ventilator and the combinationand arrangement of the various parts, substantially as will behereinafter more fully described and claimed.

In the drawings Figure 1 is a side elevation of a freight car providedwith my improved ventilator; and Fig. 2 is an enlarged detail Viewofsaid ventilator.

In said drawings a represents the car to the 3o roof or sides of whichis secured the ventilator b. The ventilator consists of an outer tube oprovided with openings g linto the interior ot the car through the tubesn and the movable tubes m attached to the ends of said tubes n at anobtuse angle thereto.

All of these tubes m are connected together by the rod o so that theirpositions may be changed when the direction in which the car is runningis changed as will hereinafter be 4o more fully explained. One end ofsaid tube c communicates directly with the external air. Within the tubec and extending almost its entire length is arranged the smaller tube hprovided at one end with a removable funnel lo communicating with theexternal air. The funnel 7c is of sucl1,construction that when it isplaced on either end of the tube h it tightly closes one end of the tubec.

Removably secured to one end of the tube 5o c is a funnel shapeddischarge e terminating in the enlargement c.

(No model.)

In operation when the car is running in the direction indicated by thearrow in full lines, the discharge funnel c and inlet funnel 7c occupythe positions shown in full lines in the drawings. The air currententers pipe h through funnel 7o and will when leaving said tube h andentering the funnel shaped discharge e e of tube c produce in said tubec" a vacuum or suction whereby foul air 6o is drawn from the car throughtubes -m n into said tube c and discharged at the outlet e thereof. Theenlargement e at the end of e will in its passage through the airincrease the vacuum or suction as will be manifest. If the direction inwhich the car is traveling be reversed, the funnels 7o e are removed andplaced on opposite ends of the tubes h" o as indicated by dotted linesin the drawings. The tubes mare at the same time turned by 7o rod o atan angle ot' about one hundred and eighty degrees to the positionformerly occupied by them. If desired a blower may be used in connectionwith the ventilator by simply attaching the inlet funnel lc to theoutlet tube of said blower.

It is manifest that modiiications of my improvement may be made withoutdeparting from the spirit of my invention.

Having thus described my invention, what 8o I claim is- The combinationin a car or similar ventilator of an air tube c provided with a seriesof movable tubes m n communicating with the interior of the car andhaving at one end a discharge e e leading to the exterior of the car,with the tube h incased by said tube c and having at one end a receivingfunnel lo in communication with the external air and having its otherend open and situated 9o near the discharge end e e of the incasing tubeo', substantially as described.

In testimony that I claim the foregoingI have hereunto set my hand this12th day of August, 1892.

MARTIN ROSE RUBIIE.
